LEON STEIN, OF PASSAIG, NEW JERSEY.

SHEET-METAL ROOFING.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed August 17, 1907. Serial No. 389,081.

To all whom it, may concern.

Be it known that I, LEON STEIN, a citizen of the United States, residingat Passaic, in,

the county of Passaio. and State of New Jersey, have invented certainnew and useful Improvements in Sheet-Metal Roofing, of which thefollowing is a specification. This invention pertains to certain new anduseful improvements in sheet metal roofs,

and has or its object a roof construction which completely eliminatesthe use of wood as a support, and which provides a mode of joining orfastening the sheets which allows lar view of one of the sheets lookingup towards the under side thereof, Fig. 5, is an end elevation of theform of sheets used at the apex of the gable portion of the roof, Fig.6,

' is a pers ective view of one of the sheets in 'det'ache position, andFig. 7, is a plan view of one of the sheets employed at the roofcorners.

In practice I employ sheets each of which is formed with an invertedU-shaped ortion at one of its longitudinal sides formed y first bendingmetal upwardly at an incline as at D,

then outwardly parallel with the body of the sheet as at E, thendownwardly at an incline as at F, and finally in turning over thelongitudinal edge of the sheet as at G. The 0 pcsite longitudinal sideedge of the sheet is ent upwardly at an incline and as at H, and

turned over on its longitudinal edge as at I. As depicted in Fig. 3, thepart H of one sheet 'enters into the space between the parts D F, of theadjacent sheet, thus forming a perfect water tight joint which freelypermits expansion and contraction of the parts without disrupting suchjoint; The front portion J, of each of the front 1 sheets A, is extendeddownwardly at an inand s aced from the under face 0 the sheet clinetothe bod of the sheet and is then turned rearwar y as at-K, to lieparallel with and but slightly spaced from portion J. PartK, is extendedrearwardly arallel to as at and is then bent in U-shape to provide1pockets M, for receiving the securin bars These bars E, are made ofsteel an of suflicient length to serve as connectors between the severalsheets, which are disposed transversel to the len th of the latter.

As clear y illustrate in Fi 2, the adjacent sheets have their en soverlapping which is made ossible by formin the rear sheets B, withtheir pockets for ro E, to the rear of thefront edge thereof, clearlyshown in Fig. 4. Thus it is obvious that the several sheets A, and B arefirmly secured to the rods E, and to one another.

5, shows one of the form of sheets used at the apex of the gable, inthis construction the sides C, C, are formed of an integral pieceofmaterial and. have the rod receiving pockets E, formed by extensions Nwhich are turned under and extend rearwardly to lie parallel with thebod of each side C C, so as to locate ockets to the rear of the lowerends of si es C, C.

Fi 7, shows one of the corner sheets D, whic is formed with=parts O andP similar to the inverted U-shaped parts of the sheets A and B and whichoverlap with the latter in the same manner as shown in Fig. 2, whereinsheets A and B are so related.

It will be apparent that no wood whatever is involved in theconstruction. Moreover all fastenin of any nature are dis ensed with,with t e exce tion of the metal ars E. At the same time t e jointsefiected between the sheets are such that not only is a water proofunion provided, but furthermore one wherein expansion and contraction ofthe sheets may take 'place without injury to or disruption of the oints.

What is claimed is:

In a metal roof, sheets each com osed of a body havin one of its sidesindlined upwardly and fiaving its edge turned over, and having itsopposite side bent upwardly at an incline then outwardly to lie arallelwith the body, and finally downwar y at an incline and havin its freeedge turned in, said first named inc ined side of one sheet extending inthe space formed by the two inclined portions at the side of theadjacent sheet.
